<Mac Mini M1 No sound on HDMi

Mac Mini M1 running ventura 13.5.2. I have 2 monitors connected. One through HDMi on the device iteself and a second through an expansion unit. No matter what I do I cannot get sound through the monitors. Only through built in speakers. When I go to sound settings it shows the monitors connected via HDMi but the output volme is "greyed out" I have another mac mini the same and I do not even get the option to play sound through HDMi

No solution seems to be available?

Mac mini (M1, 2020)

Sorry if this is too obvious, but sometimes it's the obvious things... what are the actual monitors? Do they have speakers? I just remembered that I have a Samsung SMBX2431 display, connected via HDMI right now on my desk - this display has no built-in speakers; it has an audio-out port to which I could attach speakers. If I just send sound out to this monitor, nothing comes out because, well... no speakers.

Was running Ventura 13.6 and now Sonoma 14.0 on M1 Mac Mini with Asus VP278 Monitor via Direct HDMI Cable between both

ALL sound Levels are passed totally to the Internal Speakers of the Asus Monitor

To adjust should levels requires using the Asus Builtin Controls

Have you checked your Audio Midi Setup utility in Applications -> Utility and made sure you are at 16 bit 44.1kHZ before selecting the monitor, and stays put at that when you select the monitor?

Are you using a direct HDMI cable, or an adapter to USB-C?

Does the monitor support thunderbolt?

It is normal that the volume is greyed out. Do the monitors themselves have a volume control of some form (button, slider, menu)? If your mac says that the sound output is set to one of your HDMI monitors, then it probably is. FWIW, I work with several monitors and TV connected via HDMI and never had a problem - just set sound output to the desired device and control it there.
